What about doing a system restore?
A system restore can only be done if EEPC was not the last product. If it is, it will break the system.
EEPC is installed on Hardisk and BIOS is normally on firmware/ROM, So basically it's should not a problem..
How you do system restore?
if it after booting into EEPC should be no issue.. unless you;re restoring something that related with EEPC, like it's file /driver etc..
